Web Infecting Trojans Cause Problems in Europe
As per the monthly report of ESET for June, the widespread computer threats exhibited several emerging trends. One of the main threats that spread in nearly all the European countries was a web infecting Trojan.
Technically, it is a script inserted into the web pages that automatically redirects users to IFRAME-infected websites. These IFRAME websites download script and execute other malicious codes to vulnerable systems.
ESET has classified the threat as JS/TrojanDownloader.Pegel.BR, and claimed that it got the fifth position in terms of global ranking. The threat gained a share of 2.29% of total computer threats discovered on the computers equipped with ESET security products.
Besides, different variants of Win32/Conficker continued to have been the most frequently detected threat with a share of 9.79%. The most interesting fact about Conficker was its high infection rate in Slovenia and Ireland with the detection rate at one third of the total malware discovered in respective countries. The Conficker infection in Ireland almost reached the level of double in the month of June 2010 from the earlier high of 15%.
Commenting on the issue, Urban Schrott, IT Security and Cyber Crime Analyst, ESET, said that this high infection rate was alarming and indicated to the Ireland computer users negligence to patch vulnerabilities and update their operating systems. For instance - a simple Microsoft patch could give protection from Conficker infection. Considering the rising infection rate, Irish computer users seemed to have no awareness about computer security practices, as reported by Silicon Republic on July 7, 2010.
However, the global infection rate of Conficker in June 2010 was below 10%. The worm caused huge damages to IT systems of several organizations as it was launched in released after the gap of two years. Schrott said that the rising popularity of Conficker and patch for exploited vulnerabilities should have contributed to its decline.
Besides, the INF/Autorun gained the share of 6.57% and Win32/PSW.OnLineGames (4.26%). The fourth place was captured by Trojan variants from the Win32/Agent family that steal user data and accounted for the share of 4.26%.
The security experts said that it was possible to avoid falling victims to most of the malware infection by following safe practices, installing system patches, updating security products, disabling Autorun and by avoiding unprotected share folders.
